ABSTRACT:
Fever
of unknown (FUO) origin challenging clinical condition. The causes of FUO are
diverse: possible etiologies include infectious diseases, chronic granulomatous
diseases, malignity, connective tissue disorders and vasculitis. Giant cell
arteritis which affects the aorta and its main branches, contributes up to 17%
of cases with fever of unknown origin above age 50. There is increasing
evidence for a role for18F-FDG
PET/CT in the diagnosis of vasculitis and18F-FDG PET/CT is a useful technic for evaluation of the FUO. Clinical studies show
that FDG-PET is a useful diagnostic aid in obscure cases of fever of unknown
origin. We report here a case of a 54-year-old woman who present to our clinic
with FUO due to giant cell vasculitis.
